Answer:
76°
Explanation:
two parallel lines intersected by a transversal create several types of angle pairs - some of which are equal to each other, and some of which are supplementary
in this problem, ∠BCD ≅ ∠ BFG because they are 'corresponding'
therefore you can create this equation
x + 26 = 2x - 24
26 = x - 24
x = 50
substitute into '2x-24': 2(50) - 24 = 76
